Benefits of technology

[0027]The method can further comprise applying one or more substances to enhance pathogen controlling effects, such as, for example, an adherent substance to prolong the adherence of the product to the plant.
[0028]Advantageously, the present invention can be used without releasin...

Problems solved by technology

Typically, these leaves will develop yellowish spots on them, adding to their mottled appearance, and the plant can be stunted in growth, particularly if infected early in the season.
While mosaic virus might not kill a plant, its effect on the growth and overall health of the plant can greatly affect the amount of economically valuable products delivered by a crop.
For example, fruits might become too bitter to be edible, or coloration, quality, or ripening of fruits can be disrupted.
Furthermore, the virus spreads particularly easily when conditions are damp.
In addition to viral plant pathogens, bacterial plant pathogens can cause severe and economically damaging diseases as well.
Symptoms of an infection with some of these pests can include spots, mosaic ...

example 1

pid Fermentation

[0160]For this invention, a natural mixture of sophorolipids is synthesized by fermentation of S. bombicola in a fermentation medium containing 100 g glucose, 5 g yeast extract, 1 g urea and 100 g canola oil in 1000 ml of water. After 5-7 days of fermentation, sophorolipid is collected by precipitation. After adding additional amounts of the same nutrient medium, fermentation continues for another 3 days, after which another portion of SLP is collected.

[0161]Two different products are produced from this fermentation process: one comprising pure SLP and one comprising S. bombicola culture containing SLP.

example 2

on of SLP Solution for Foliar Treatment

[0162]Precipitated SLP obtained by S. bombicola fermentation can be used to produce a product for treatment of plants for all types of mosaic viruses. The precipitated SLP usually contains up to 50% water; however, no further concentration is needed prepare this type of treatment product. The treatment product contains from 0.1 to 0.5% (v / v) of the unpurified SLP.

Example 3—Preparation of SLP Solution Containing S. bombicola Cells for Foliar Treatment

[0163]Another type of treatment product can use the S. bombicola culture to treat mosaic viruses, as well as other microbial pathogens, such as pathogenic Gram-positive bacteria. The culture can be produced in portable, distributable reactors, which can provide for local production of the product in close proximity to an application site.

[0164]The cultivation process produces 250 gallons of pure S. bombicola culture containing up to 4 g / L of SLP. The resulting culture is diluted at least 10 times, p...

of Cucumber Plant Infected with Mosaic Virus

[0165]The subject invention was used to treat cucumber plants infected with a mosaic virus. The leaves of the cucumber plants were treated with a composition comprising 0.2% SLP. The SLP composition was sprayed onto the surfaces of the leaves for a period of three days.

[0166]The mosaic spots present on the leaves disappeared and the leaves looked healthy in less than five days after the beginning of treatment.

Abstract

Compositions and methods are provided for treating certain plant pathogens using microbe-based products. In particular, the subject invention relates to treatment of plant pathogenic viruses, including mosaic virus, as well as plant pathogenic bacteria, using beneficial microbes and/or their growth by-products. In certain embodiments, the growth by-products are biosurfactants.

Description

CROSS-REFERENCE TO A RELATED APPLICATION[0001]This application claims the benefit of U.S. provisional application Ser. No. 62 / 564,517, filed Sep. 28, 2017, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]Mosaic viruses are a group of plant pathogens that affect, and can cause significant damage to, more than 150 different types of plants. Millions of growers have had portions of, or even entire crops destroyed by mosaic viruses. The most common crop plants that can become infected by mosaic viruses include potatoes, gourds, okra, chili peppers, cucumbers, muskmelons, pumpkins, tomatoes, tobacco, roses, tulips, beets, plums, beans and many more.[0003]There are multiple species of virus that fall under the category of “mosaic” diseases, each of which belongs within one of a variety of genera, for example, Begomovirus (e.g., cassava mosaic virus), Polyvirus (e.g., plum pox virus), Tobamovirus (e.g., tobacco mosaic virus) and to a number of oth...
